Tribelopoma amygdala was named by Jacquet et al. (2016) [Shell asymmetrical, low, almond-shaped outline ranging from subcircular to elongate ovoid with narrowest curvature at supra-apical margin. Shells range from 4.5–13.2 mm maximum length (mean = 9.91 mm; n= 17) and 2.9–9.9 mm maximum width (mean = 7.43 mm; n = 15); mean width:length ratio of 0.72 (n = 14). Apex located eccentrically to sub-centrally, offset from shell midline, level with the widest part of the shell. Sub-apical margin more broadly convex than supra-apical margin; greatest curvature to one side or other of the shell midline. First order external ornament consists of 10–22 (mean 15) concentric, irregularly spaced, commonly bifurcating, grooved angular rugae. Individual rugae from 124–317 μm in width. Second order external ornament consists of fine radial lirae in some specimens.]. Its type specimen is SAM P525224, a shell, and it is a mold. It is the type species of Tribelopoma.
